Brotherly techno duo Paul & Fritz Kalkbrenner are perhaps best known for "Sky and Sand," which featured in the smash 2008 film _Berlin Calling_ (which Paul also starred in). The track became an anthem when BPitch Control released it as a single a year later. On this episode, Vivian Host sits down with Dirty Doering – a mainstay of shuttered Berlin club Bar 25, which featured in Berlin Calling – to discuss the explosion of rave tourism in the late 2000s and the film's legacy.
